Key points for selecting solenoid valve products: 1. The main control parameters for selecting solenoid valves include diameter, design nominal pressure, allowable temperature range of the medium, interface size, etc. 2. Electromagnetic valve is a type of valve that uses an electromagnet to push the opening and closing of the valve. It is usually used in two position control with a diameter of less than 40mm, especially for connecting, cutting off or switching gas and liquid circuits. The sealing performance of valves is one of the main indicators for assessing the quality of valves. The sealing performance of valves mainly includes two aspects, namely internal leakage and external leakage. Internal leakage refers to the degree of sealing achieved between the valve seat and the closing component for the medium. External leakage refers to the leakage of the valve stem packing, the leakage of the middle gasket, and the leakage caused by casting defects in the valve body. Leakage is not allowed to occur. The main advantages of solenoid valves are small size, reliable operation, and easy maintenance,. When selecting, it is important to choose between normally open or normally closed types according to the process requirements. Key points for construction and installation of SMC solenoid valve

The installation position and height of SMC solenoid valve must meet the design requirements of the port direction, and the connection should be firm and tight. Simplify the control circuit; In the past, pneumatic and electric control circuits were widely used in actuators, which increased the complexity of the system. However, pilot operated solenoid valves form a control circuit inside the valve that utilizes the working medium itself, with a very simple structure. In the past, multiple technical parameters of solenoid valves at home and abroad were still limited, and the diameter of solenoid valves in China has been expanded to 300000 mm; The medium temperature ranges from -200 ℃ to 450 ℃; The working pressure ranges from vacuum to 25MPa. The action time ranges from tens of seconds to a few milliseconds. Two position control quick shut-off valve and pneumatic switch valve, electric switch valve, can also partially replace continuous adjustment pneumatic and electric control valves. Foreign industries such as textiles, light industry, and urban construction have extensively adopted solenoid valves, while metallurgical and chemical industries are increasingly using solenoid valves in auxiliary systems. Domestic automation professionals are increasingly paying attention to solenoid valves. When simplifying the operation of the automatic control valve in the pipeline system, some auxiliary valves and fittings must also be equipped on the pipeline. Isolation bypass is a typical installation method that requires three manual valves, with manual valve 1 being the bypass valve and manual backup. And manual valves 2 and 3 are isolation valves, ensuring online maintenance of automatic control valve 5. Of course, two tees 4 and a flexible connector 6 are also required. This piping system takes up a large amount of space, is time-consuming to install, and is prone to leakage. The ZDF series multifunctional solenoid valve cleverly eliminates these additional accessories and still has the function of isolating the bypass. A filter needs to be installed in front of the automatic control valve. When multiple self-control valves are used in combination, it is often necessary to install one-way valves to prevent interference between pipelines. Unidirectional solenoid valves, combination solenoid valves, and filtered solenoid valves have all played a role in simplifying pipelines.
